    摘要: A process for preparing a high-density granular detergent product by dry neutralizing alkylbenzene sulfonic acid with a particulate mixture of a water-soluble alkaline inorganic material, for example, sodium carbonate, and a hydratable inorganic detergent builder in an apparatus which provides both mixing and shearing of the particulate mixture, e.g. a V-Blender, thereby forming the granular detergent product. The process includes the addition of particles of pH sensitive detergent surfactant, such as alkyl sulfate, into the particulate mixture prior to the addition of the alkylbenzene sulfonic acid. The high-density product has good product homogeneity and surfactant solubility, and essentially no reversion of the alkyl sulfate to the corresponding fatty alcohol due to acid-catalyzed hydrolysis. Other pH sensitive detergent surfactants include alpha-sulfonated fatty acid alkyl ester and polyhydroxy fatty acid amides.

    摘要: A process for the production of pourable, free-flowing granules which are suitable for use as wetting agents, detergents or cleaning products from aqueous solutions or suspensions of such materials in a fluidized-bed spray granulation apparatus employing a hot fluidizing gas. The aqueous selections or suspensions are dried with superheated steam as the fluidizing and drying gas wherein the drying step is carried out in a closed-loop system comprising a steam circuit from which the water evaporated from the aqueous solutions or suspensions of starting materials is removed as a partial stream and the thermal energy released is returned to the steam circuit. The granules are discharged from the granulation apparatus before they can be damaged by heat.

    摘要: A process for preparing a concentrated detergent composition useful in automatic machine dishwashers comprising preparing a dry mixture of a thickening polymer and a sodium trimetaphosphate builder, then adding the dry blend to water and subsequently adding a potassium hydroxide base to form a homogeneous solution. Sodium silicate and optional ingredients are then added to the process. Compositions resulting from the process contain a K+/Na+ weight ratio of greater than about 0.5 to about 1 and a viscosity of from 1,800 to about 3,500 cps.
